Molecular characterization of nucleus-localized RNA-binding proteins from higher plants.
Article in Plant molecular biology, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We report the isolation and characterization of genes from the higher plants Arabidopsis, spinach and tobacco which code for nucleus-localized RNA-binding proteins. Common features of these polypeptides are glycine/arginine-rich regions with several RGG repeats at their N- and C-termini, which are sufficient for RNA binding in northwestern assays. All polypeptides analysed contain two basic bipartite nuclear localization signals and translational fusions harbouring these regions with the beta-glucuronidase gene direct the fusion proteins into the nucleus. Nuclear localization was confirmed by cellular fractionation with a polyclonal antiserum raised against the over-expressed tobacco protein NtRGG1p. Two or three copies of related RGG genes appear to be present in the analysed organisms and the expression of some of them is regulated: a tobacco gene is light-regulated and a spinach gene is preferentially expressed in roots. Possible biological functions of this class of RNA-binding proteins as well as structure/function relationships related to the modular structure are discussed.
